Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/47
Filed: 1936-02-05
Abstract: 469,677. Cigarette-making machines. BERND, A. Feb. 5, 1936, No. 3399. [Class 130] Bands of cork &c. are wrapped around lengths of cigarette rod and mouthpiece portions, assembled in alignment, by means moving axially along the assemblage which is carried laterally by a conveyer. The mouthpiece portions may be formed by filter tips or by tobacco. As shown in Fig. 1, assemblages comprising pairs of cigarettes 1 with interposed filter tips are fed axially into a channelshaped member 3 which is carried by a cam 4a into engagement with arms 5a on an intermittently rotatable drum 5 which is locked during the stationary periods. Each assemblage is held upon its arm 5a by suction transmitted through holes 5d and is carried into contact with a pasted wrapping band 7 fed on a suction drum 8. A channel-shaped member 9 carried on slides 10 is moved towards the drum 5 to wrap the band 7 partly around the assemblage. After the suction in the drum 5 has been cut off by a member 5i the assemblage is transferred into a groove 11a in an intermittently rotatable drum 11 by suction exerted through bores 11b. The drum carries the assemblages beneath wrapping members 12a, 12b which are reciprocated along guides 12f by a crank and move in opposite directions over successive assemblages. Stops prevent axial movement of the assemblage during the operation of the wrapping members. The united assemblage is bisected by a knife 14 while being carried beneath a guide 13 by the drum 11 and the cigarettes are discharged on to a belt 15. In the construction shown in Fig. 3, the lengths of cigarette rod and the filter tips are fed from hoppers into grooves 16a in a drum 16 in which they are retained by guides 17 until they are transferred to suction arms 5a on a continuously rotatable drum 5. A rotary member 18 having grooves 18a presses the wrapping band 7 partly around the assemblage before it is transferred and held by suction in a groove 19h in a block 19a mounted on a continuously rotating carrier 19. The wrapping means are formed by members 23b, 23c which are slid along cross-bars 24 by rollers 23a engaging cam grooves 25a in a stationary cylinder. At the discharge position the suction is cut off by a member 22a and the united assemblage is blown out of the groove 19h beneath a guide 27 on to the belt 15 by compressed air admitted through a pipe 26. In a modified construction the assemblages are carried by an endless chain structure and the movement of the wrapping devices is effected by a ramp.

Title: Improvements in or relating to radio beacon systems
IPC: G01S1/50
Filed: 1947-02-05
Abstract: 642,182. Radio navigation. PHILIPS LAMPS, Ltd. Feb. 5, 1947, No. 3435. Convention date, Feb. 5, 1944. [Class 40 (vii)] Relates to phase beacon systems in which two radio fields are established, the modulation phase of one field being proportional to azimuth and the modulation phase of the other (reference) field being independent of azimuth so that the bearing of a mobile receiver relative to the beacon may be determined by comparing the phases of the two modulation signals. According to the invention the two modulation frequencies are harmonically related, the bearing-dependent modulation signal having the higher frequency. As shown in the Figure, a modulation frequency nw obtained by frequency multiplying the output from the oscillator 7 is applied in phase quadrature to the balanced modulators 5 and 6 together with a carrier from the source 1, the outputs from the modulators being applied to two crossed pairs of vertical aerials 13, 15 and 14, 16 and a carrier frequency is also applied to the central aerial 17 from the modulator 4 so that a resultant field is established with a modulation phase proportional to azimuth. The frequency w is also applied from oscillator 7 together with a carrier frequency from 1 to the modulator 4 the output from which is applied to the central aerial 17 to establish the omnidirectional reference field. At the mobile receiver, Fig. 2 (not shown), the two modulation frequencies are separated by filters and the reference frequency w is multiplied by a factor n and then applied to a phasemeter together with the bearing- dependent frequency nw. Specifications 594,532, 642,094, 642,181 and 642,183 are referred to.

Title: Apparatus for determining displacement
IPC: G01D5/36
Filed: 1972-01-25
Abstract: 1368204 Measuring displacement BENDIX CORP 25 Jan 1972 [25 Jan 1971] 3543/72 Heading G4H In digital displacement measuring apparatus of the type utilizing a displacement encoding scale for detecting the amount and direction of the displacement, the least significant digit is derived when the scale is stationary. As described (Figs. 1A, 1B) the relative movement of index and scale gratings 11, 12 is detected by four phase displaced photo-cells 21-24, the outputs from which are fed by differential amplifiers (to reduce errors due to disturbances in the grating patterns) to a resistive phase divider 31 delivering ten phase displaced signals via Schmitt trigger circuits 33 to a pulse forming and direction sensing circuit 35 driving a reversible counter 40. Initially a preset digit may be entered manually into an adder 55 (via a tens complimenter if a negative member is entered), added to the output of a twos complementer 51 receiving binary signals from converter 46 representing the value of the output of the Schmitt triggers and stored in a memory 56. The contents of memory 56 are subsequently added to the output from converter 46 in an adder 61, a count of 10 being added to or subtracted from the output of the adder 61 in accordance with whether it is negative or greater than 9. This signal is then complemented if the counter 40 is in its negative state and decoded and displayed together with the count 44 from the counter 40 and a + or - sign. Either the grating 11 or the grating 12 and heads 21-24 may be removable. The gratings which may be reflective or transmissive may be cylindrical, disc shaped or frusto conical. The gratings may be replaced by an interferometer or by means for deriving any form of electromagnetic energy.

Filed: 1922-02-08
Abstract: 195,819. Dickinson, W., and Dickinson, F. Feb. 8, 1922. Tipping-wagons. - In engine operated tipping-gear for motor and other vehicles, the power is transmitted to the body through a pair of inclined struts contacting with the ground. The struts A, Fig. 1, are removably pivoted to a lever C guided at one end by a slotted plate E on the chassis J, the rear inclined end of the lever being pivoted to the body frame H, which is pivoted on a cross-bar K supported on a bracket at the rear of the chassis. When the vehicle, after being positioned for tipping with the struts in place, is moved forwards, the bcdy is tipped until after the struts pass the vertical position, when the body is replaced by gravity. The struts are normally hung on hooks V connected to locking-bolts N, the weight of the struts holding the bolts in position to lock the body, against the action of springs R. Alternatively, the struts a, Fig. 2, may be pivoted in a lever c sliding in a pivoted slide e on the chassis, and pivoted to the body h, which on forward movement of the chassis is first held by the struts a and slides over the chassis on rollers or the like, so that a bar k disengages a hook m<1> and engages a hook m<2>. The slide e has meanwhile. been moved in front of the connection b so that further movement of the chassis tips the body. The engine is reversed to return the chassis and the body to their original positions, and the struts. a are hung in hooks c to cause projections t on spring-pressed latches n to lock a body plate s beneath a chassis bracket w. Flanges may be provided to prevent lateral movement of the body.

Title: Heat bodying polydiolefinic drying oils with cyclodiolefins
IPC: C09F7/00
Filed: 1953-02-11
Abstract: Improved drying oils are obtained by heating at 200 DEG  to 300 DEG C for 1 to 3 hours, 100 parts of a drying oil derived from a conjugated diolefin having from 4 to 6 carbon atoms, preferably dissolved in an inert hydrocarbon boiling between 80 DEG  and 250 DEG C., with 5 to 40 parts of a cyclodiolefin such as cyclopentadiene or methyl cyclopentadiene or their dimers.  The wetting properties of the products may be improved by reaction with up to 2.5 per cent by weight of maleic anhydride before or after the reaction with the cyclodiolefin.  Diolefins specified for preparing the drying oil are butadiene-1,3; isoprene; 2,3-dimethyl butadiene-1,3; piperylene and methyl pentadiene-1,3; and from 0 to 40 parts of styrene may also be included.  The drying oils may be prepared by continuous or batch polymerization in an inert diluent such as naphtha, mineral spirits, butane, xylene, benzene, toluene, cyclohexane, or mixtures, or a modifying diluent, e.g. butene-2, which results in limited copolymerization and chain termination. Other diluents listed are vinyl ethyl, vinyl isobutyl, diethyl and diisopropyl ethers, dioxane, anisole and phenetole.  Finely dispersed sodium is used as catalyst, preferably in conjunction with 1 to 50 per cent of a C1 to C5 aliphatic alcohol such as isopropanol or t-butanol.  Alternative catalysts are potassium, sodium hydride, sodium alloys and Alfin-type catalysts.  Acetic acid is used at the end of the reaction to destroy residual catalyst and the solution of the product is neutralized, filtered, preferably fractionally distilled and then concentrated to an intrinsic viscosity of 0.1 to 0.4.  The viscosity may be further increased by heat bodying and naphthenate or octoate driers may be added.  The improved drying oils may be used in varnishes and enamels to give films of increased chemical resistance and flexibility.
